In 1989, ProBal was formed and purchased all of the designs and intellectual property related to dynamic balancing from Stewart Warner, who had been manufacturing soft-bearing analog balancing machines since the 1950's. ProBal implemented modern microprocessor driven electronics into their machines and updated them to a hard-chassis digital product line. They experienced tremendous success with this platform through the early 2000's.
As technology advanced and modern personal computers became more accessible, ProBal Dynamic Balancing set to work to redesign their product line again updating the machines, building 3D models of the successful frame designs, and developing a Windows-based operator interface. The modernization resulted in one of the fastest and most accurate hard-bearing dynamic balancing systems available today along with a team that has a deep understanding of balancing applications ready to tailor machines to customers specific needs.
